the rod runs down the passenger side of the tranny, to a mechanical
input on that side at the rear of the box. Pulled out, towards the rear
of the car, is the "unlocked" position, as I recall being told by one
who should know.
It is likely that one of the vacuum line nipples is broken off at the
servo - but if the line is just pulled off you might be able to
reinstall it. And if the rest of the vacuum system is not leaking, the
lock/unlock function might even work again.
